Today I created a load balancer and assigned to it 3 droplets (all 3 host parse servers), but it doesn't transfer the traffic to them. It doesn’t even pass the health checks!
All 3 of my parse servers, have 22 and 1337 as their only open inbound ports.
Here's the load balancer's setup.
Any idea what is wrong?

I follow Document for Creating Content-Based Load Balancing: https://cloud.google.com/load-balancing/docs/https/content-based-example
I want to reach external address with https. I want load balancer to connect to VM with simple http.
Both VMs work as expected and are returning proper answet when reached by IP address. LB's settings seem fine. Both health checks are passing and Google SSL Certificate is ACTIVE.
However, when I try to reach Load Balancer's IP address or domain I get 502.
LB IP is 35.244.161.226 wciel.pl
Load Balancer's logs show statusDetails: "failed_to_connect_to_backend"
I attached screens of my Google Cloud Console.
Please advice.

I think there is a mismatch in back end service configuration. From the details of web-map-backend-service its seems like your service listening on port 80. However, when you have configured backend service you have configured it with port 443.
If you don't require secure communication between LB to VM, I would recommend followings:
Change backend protocol from HTTPS to HTTP
Edit backend Port numbers from 443 to 80
Save and update the configuration.
I am trying to configure my website to have a secure connection (https://) via Amazon's EC2, ELB, and Route 53.
I am running a t2.micro instance (no Elastic IP or anything). My Elastic Load Balancer has the SSL certificate attached. My SecurityGroup allows for https connections through port 443. I'm not sure what I'm doing wrong here.
All of my configurations are below. Any help is appreciated because, as it stands, I can't access my website at all.
Thank you in advance!
EC2 - - -
Load Balancer - - -
Route 53 - - -
Step 1: Hit the EC2 instance directly and verify that the health check URL responds with an HTTP 200 status code. If not, then get that working first.
You aren't clear about your security group configuration. You should have a security group on your load balancer that allows HTTP and HTTPS connections. Then you should have a security group on your EC2 instance that allows HTTP (port 80) connections from the load balancer's group.
The issue is obviously the failing health check on the load balancer at this point, so no need to look at Route 53 settings right now. You need to concentrate on getting the communication working between the EC2 instance and the load balancer to get that health check to start working. Until then the load balancer won't accept any traffic because it doesn't have instances it considers healthy that it can forward traffic to.
I have set up an instance reachable on http.
I have set up an instance group containing that instance.
I have set up Loadbalancing using an self signed ssl cert.
The external IP of the LB and the instance can be reached.
The forwarding of the request from the LB runs into an time out.
The config for Loadbalancing says "you have 0 instances without errors, you have 1 instance with errors."
I don't see any log entries in the apache logs coming from the lb frontend.
There is no http connection from Google addresses showing up.
Any ideas where to look for or hints to a good guide (not the rather good google docu)?
Yes. You can use Compute Engine HTTPS load balancer with HTTP backend services. Select HTTP as Backend services protocol. For health check, use HTTP health check. Add GCE firewall rules to open tcp:80 for 130.211.0.0/22 and tcp:443 for 0.0.0.0/0 source IP ranges.
This is my scenario.
I have two consumers server:
Server A has IP: 192.168.0.1
Server B has IP: 192.168.0.2
Both servers have configured the activemq as below:
transportConnector uri="tcp://192.168.0.X:61616"
updateClusterClients="true"
In my system, I have one load balancing server (hardware load balancing) which has IP 192.168.0.100 and load balances all requests to above servers.
In the past, my client must configure the connect url as below:
failover:(tcp://192.168.0.1:61616,tcp://192.168.0.2:61616)
to send active mq message.
In the current, we cannot send message directly to each server and must send to load balancing IP. But when I configure the url as below:
failover:(tcp://192.168.0.100:61616)
Nothing happens, we can ping to port 61616 but message cannot be sent.
I cannot use the acitvemq load balancing model because client cannot reach the child servers. Can some one help me? Can we configure the activemq to have the virtual client which have the load balanacing ip.
Thank a lot.
Currently, I found that I had researched the wrong way. OpenWire is a two way communication protocol which requried the connected point from both way. So we cannot put them in load balancing which have shared IP. Need to find another way :)
I have a PHP app deployed on Elastic Beanstalk, currently with a single instance behind a load balancer and am attempting to enable SSL. The current configuration is as follows:
-I've uploaded my certs to IAM successfully
-On the EB Console Load Balancer config "Listener Port" is off, "Secure Listener Port" is "443", and "Protocol" is set to "HTTPS"
-In my Loadbalancer, accessed through the EC2 console, Load Balancer Port/Protocol 443/HTTPS and Instance Port/Protocol is 80/HTTP (the default HTTP/80 HTTP/80 listener is still there but i've tried removing it to no joy)
-My security groups for both the load balancer and the instance are configured the same: Inbound is allowing all connections from either security group, plus inbound http on 80 and https on 443 (source= 0.0.0.0/0)
When attempting to access the url https://myurl.com, I get 503 service unavailable (server at capacity). I suspect there is an issue with my security group configuration, but can't figure out what it is (have tried referring to this thread).
Any Ideas?
I just experienced this on my ElasticBeanstalk deployment and the reason was that my elastic load balancer had 0 healthy instances in service. There's different health check settings, one that checks over HTTP:80 and one that checks over TCP:80. I haven't investigated thoroughly but for some reason the HTTP:80 setting will result in my servers being marked as unhealthy, but TCP:80 will test correctly. If this comes up again I would suggest looking in there?
